The speaker 70 outputs various sounds in accordance with the control of the control unit 10.

Next, each functional block of the control unit 10 and each database of the storage unit 20 will be described.

The action history recording unit 11 acquires the action history of the user regarding a place (hereinafter referred to as a “visited place”) to which the user who is the driver of the own vehicle has visited in the past, and stores the action history in the storage unit 20. Record as DB22. Specifically, the action history recording unit 11 acquires an ignition signal of the own vehicle, determines that the user has got on the own vehicle when the ignition signal is turned on, and when the ignition signal is turned off, the user takes the self Judged that the vehicle got off. Then, according to the timing of getting on or off, the current date and time and vehicle position, and the type of facility corresponding to the vehicle position are specified and recorded in the action history DB 22.

FIG. 2 is a diagram showing an example of the action history DB 22. As shown in FIG. The action history DB 22 has fields of trip ID 221, date and time 222, boarding / dismounting 223, position 224, POI 225, and destination 226. FIG. 2A shows an example of the action history DB 22 when, for example, the user goes from work at home to work and returns to work after work. FIG. 2B shows an example of the action history DB 22 when, for example, the user leaves home and visits a convenience store and then goes to a golf course.

The trip ID 221 stores an ID number for managing, as one trip, a series of action histories from when the user leaves home to when he returns to home. That is, when the user has visited a plurality of places before leaving home and returning to home, the same ID number is assigned to the trip ID 221 for each record of the action history DB 22 representing each visited place. Stored.

In the date and time 222, the date and time when the record is recorded in the action history DB 22 is stored. That is, the value of the date and time 222 in the record recorded in response to the turning on of the ignition signal represents the departure date and time when the user got on the vehicle and left the visited place corresponding to the record. On the other hand, the value of the date and time 222 in the record recorded according to the turning-off of the ignition signal represents the arrival date and time when the user arrived at the visited place corresponding to the record and got off the vehicle.

The boarding / dismounting 223 stores a value indicating whether the record is recorded in the behavior history DB 22 when the user gets in or out of the vehicle. Specifically, in the record recorded in response to the turning on of the ignition signal, “boarding” indicating that it was recorded when the user got in is stored in the boarding / dismounting 223. On the other hand, in the record recorded in response to the turning-off of the ignition signal, “disembarking” representing that the user has recorded when disembarking is stored in the boarding / dismounting 223.

The position 224 stores a value indicating the position of the visited place corresponding to the record, for example, latitude and longitude indicating the position coordinates of the visited place. Specifically, the position of the vehicle when the record is recorded in the action history DB 22 is stored in the position 224 as a value indicating the position of the visited place.

The POI 225 stores types of facilities (POI) of visited places corresponding to the record, for example, "home", "working place", "golf course", "convenience store" and the like. The action history recording unit 11 refers to the map DB 21 to identify a facility corresponding to the vehicle position when the record is recorded in the action history DB 22 and stores the type of the facility in the POI 225. A specific facility name, such as “A golf course” may be stored in the POI 225. Further, with regard to the home and the place of work, the determination may be made based on the information of the home and the place of work registered beforehand by the user, or by analyzing the action history DB 22.

The destination 226 stores a value indicating whether the visited place corresponding to the record is set as the destination. Specifically, the on-vehicle apparatus 1 has a car navigation function of searching for a route from the departure place to the destination set using the map DB 21 and guiding the host vehicle to the destination. When the user drives the own vehicle using the car navigation function, the action history recording unit 11 determines that the visited place corresponding to the record is the destination in the record recorded in the action history DB 22 after arrival at the destination. A predetermined flag value indicating that it is set to is stored in the destination 226. In the example of FIG. 2B, “O” indicating that the flag is set is stored in the destination 226 of the record of the first line where the POI 225 is “A golf course”. That is, it can be understood that the user has driven the vehicle to the A golf course by using the car navigation function in which the A golf course is set as the destination.

Each time the ignition signal of the host vehicle is turned on or off, the action history recording unit 11 acquires information of the content as described above as the action history of the user regarding the visited place, and records the information in the action history DB 22. At this time, as illustrated in FIG. 2, it is preferable that the action history recording unit 11 record a newer action history in a higher rank record in the action history DB 22. In this way, when reading out the action history from the action history DB 22, it becomes easy to preferentially read out a new action history. Furthermore, about the action history which passed for a fixed period or more, you may delete from action history DB22.

The external information acquisition unit 12 communicates with the external information device using the communication unit 40 to externalize the information on the place where the user is going to go (hereinafter referred to as “destination place”) and the schedule information of the user. Get as. For example, weather information of a destination location, congestion information of a road between the vehicle position and the destination location, and the like are acquired as external information regarding the destination location. Further, the schedule information of the user is acquired as external information, for example, information registered in advance by the user in the server or the portable terminal.

The action estimation condition creating unit 13 estimates an action of the user based on the action history of the user recorded in the action history DB 22 or the external information acquired by the external information acquisition unit 12. Create For example, in the action history DB 22, when the action history indicating that the user has arrived at a specific facility is regularly recorded in substantially the same time zone over a certain number of days in a week, the facility It is a user's work place, and it can be estimated that the user will come to work at that time zone in the future. In addition, when an action history indicating that the user has arrived at a specific facility is regularly recorded, it can be estimated that the user will regularly go to the facility in the future. Furthermore, when facilities of the same area are set as destinations on holidays of the same time almost every year, it can be estimated that the user travels regularly with the area as a travel destination. The action estimation condition creating unit 13 analyzes the action history DB 22 and extracts the action history pattern of the user for each action content, thereby estimating the action according to the action content for the destination place where the user is going to go Conditions can be created. At this time, weather information and traffic jam information acquired as external information may be combined. Furthermore, also from the user's schedule information acquired as external information, it is possible to create an action estimation condition according to the action content for the destination place where the user is going to go. The behavior estimation condition created by the behavior estimation condition creation unit 13 is recorded in the behavior estimation condition DB 23 in the storage unit 20.

FIG. 3 is a diagram showing an example of the action estimation condition DB 23. The action estimation condition DB 23 has fields of an action type 231, an action content 232, and a condition 233.

In the action type 231, a value indicating whether the record represents an action estimation condition for the action immediately before the user or the action for the future is stored. Specifically, in the record representing the action estimation condition used to estimate the action immediately before the user, “immediately” is stored in the action type 231, and the record representing the action estimation condition used to estimate the user's future action The “future” is stored in the action type 231.

The action content 232 stores specific action content of the user estimated by the record, such as “golf”, “shopping”, “lunch”, “going to work” and the like. In the record in which the action type 231 is “immediately before”, the action content estimated to be performed by the user immediately before is stored in the action content 232, and in the record in which the action type 231 is “future” The estimated action content is stored in the action content 232.

The conditions 233 store the contents of specific conditions for selecting the record as an estimation result for the user's action. The condition 233 includes, for example, the type of facility (POI), date and time, stay time, content of weather forecast for a specific area, content of traffic condition for a specific road, and the like. In the record in which the action type 231 is “immediately before”, the content of the condition set in advance in the in-vehicle apparatus 1 is stored in the condition 233. On the other hand, in the record in which the action type 231 is “future”, the content of the action estimation condition created by the action estimation condition creation unit 13 is stored in the condition 233.

When the behavior estimation condition creating unit 13 creates the behavior estimation condition, it stores “future” in the behavior type 231, and stores a record in which the specific content is stored in the condition 233 in the behavior estimation condition DB 23. In addition, as will be described later, the action contents represented by the action estimation condition stored in the action estimation condition DB 23 correspond to the messages stored in the message DB 24, respectively. Therefore, in the action estimation condition DB 23, the record initialized in association with the message DB 24 is stored in advance, and when the action estimation condition is created by the action estimation condition creation unit 13, the condition 233 is updated according to the content You may do so.

The action estimation unit 14 estimates the action of the user based on the action history of the user recorded in the action history DB 22 and the action estimation condition recorded in the action estimation condition DB 23. Specifically, a record of the action history regarding the latest visited place recorded in the action history DB 22 and each record of the action estimation condition recorded in the action estimation condition DB 23 are compared, and either action estimation Determine if the condition is met. At this time, external information acquired by the external information acquisition unit 12 may be used as needed. As a result, when the action history regarding the latest visited place satisfies any one of the action estimation conditions, it is estimated that the user has performed action content corresponding to the action estimation condition immediately before or after. It should be noted that whether the action is the last action or the future action can be determined based on whether the action type 231 of the record in the action estimation condition DB 23 is “immediately before” or “future”. Moreover, although the action estimation part 14 can estimate not only the action of a user's last action but the action which the user took at any time in the past, below, the action which the user which the action estimation part 14 estimates estimates was performed in the past Is described as the last action.

The message output unit 15 outputs a message corresponding to the action of the user estimated by the action estimation unit 14 by voice via the speaker 70 based on the message DB 24. The message DB 24 stores messages corresponding to the action content for each of the action estimation conditions stored in the action estimation condition DB 23. When the action estimation unit 14 estimates the action content of the user, the message output unit 15 extracts a message corresponding to the action content from the message DB 24. Then, the voice of the extracted message is reproduced and output from the speaker 70.

FIG. 4 is a diagram showing an example of the message DB 24. As shown in FIG. The message DB 24 has fields of a message ID 241, an action type 242, an action content 243, a message 244, an output timing 245, and a cancel 246.

The message ID 241 stores an ID number corresponding to the record.

The action type 242 stores a value indicating whether the record represents a message for the user's last action or a future action. Specifically, “preceding” is stored in the action type 242 in the record representing the message for the user's last action, and “future” is stored in the action type 241 in the record representing the user's future message. The action type 242 corresponds to the action type 231 in the action estimation condition DB 23 of FIG. 3.

The action content 243 stores, for example, “golf”, “shopping”, “lunch”, “going to work”, and the like as the estimation result of the specific action content of the user for whom the message output by the record is performed. The action content 243 corresponds to the action content 232 in the action estimation condition DB 23 of FIG. 3. That is, in the record in which the action type 242 is "immediately", the action content presumed to be performed by the user immediately before is stored in the action content 243 as the output target of the message by the record, and the action type 242 is "future" In the record, the action content estimated to be performed by the user in the future is stored in the action content 243 as an output target of the message by the record.

The content of the message output from the message output unit 15 is stored in the message 244 according to the record. The contents of the message 244 are preset for each record in accordance with the combination of the action type 242 and the contents of the action content 243. For example, in the first record where the action type 242 is “immediately before” and the action content 243 is “golf”, “a good score is given as a message when it is estimated that the user has stayed at the golf course immediately before Content is stored in the message 244. Similarly for the other records, appropriate message content is stored in the message 244 for each user's action timing (immediately or later) and action content.

The output timing 245 stores the timing at which the message output unit 15 outputs a message according to the record. For example, in a record in which the action content 243 is "meeting", information indicating 10 minutes before the scheduled meeting start time as a message output timing is output in order to output a message at an appropriate timing before the start of the conference. It is stored at timing 245. In the case of a record in which nothing is defined at the output timing 245, immediately after the action estimation unit 14 estimates the action of the user, that is, immediately after the action estimation unit 14 determines that any action estimation condition is satisfied. Output a message. For example, in a record in which the action content 243 is “purchase present”, nothing is specified in the output timing 245 in order to output a message immediately after the user's action is estimated. Thereby, the message can be output at an appropriate timing according to the user's future behavior.

The cancel 246 stores a value indicating whether the user has canceled the message of the record. When the message output unit 15 outputs a message, if the user determines that the message is unnecessary from now on, the user can instruct cancellation of the message. When the user instructs cancellation of the message, a predetermined flag value is stored in the cancellation 246 of the record corresponding to the message. If the flag is set in the cancel 246, the message output unit 15 determines that the message by the record is unnecessary for the user, and does not output the message thereafter. In the example of FIG. 4, “o” indicating that the flag is set is stored in the cancellation 246 of the third line of the record in which the value of the message ID 241 is 3. That is, it can be understood that the user has determined that the message represented by this record is unnecessary.

When one of the records stored in the action estimation condition DB 23 is specified as the user's action estimation result by the action estimation unit 14, the message output unit 15 matches the action type 231 and the action content 232 of the record, respectively. Records in which the content is stored in the action type 242 and the action content 243 are searched in the message DB 24. Then, by outputting from the speaker 70 a voice based on the content of the message 244 of the retrieved record, the message output according to the action estimation result is performed. However, as described above, when the flag is set in the cancel 246 in the retrieved record, the message is not output.

The cancel unit 16 sets a flag for the cancel 246 of the action estimation condition message DB 24 shown in FIG. 4 according to the user's cancel instruction. As a result, the cancel unit 16 prevents the message output unit 15 from outputting the message canceled by the user once. The user can issue a cancellation instruction to the cancellation unit 16 by performing a predetermined operation using the operation input unit 60.

Next, the processing content of the control unit 10 will be described. FIG. 5 is a diagram showing a process flow of the control unit 10.

In step S10, the control unit 10 determines whether the ignition signal of the host vehicle is turned on. If the ignition signal of the host vehicle is turned on, the process proceeds to step S20. If the ignition signal is not turned on, the process proceeds to step S100.

In step S20, the control unit 10 acquires the current position of the vehicle from the vehicle position detection unit 30.

In step S30, the control unit 10 refers to the map DB 21 to identify a facility (POI) corresponding to the current position of the vehicle acquired in step S20.

In step S40, the control unit 10 records the user's action history in the action history DB 22 by the action history recording unit 11 based on the current position of the host vehicle acquired in step S20 and the facility specified in step S30. . At this time, the action history recording unit 11 uses the current date and time as the date and time 222, “rides in” the boarding / dismounting 223, a coordinate value corresponding to the current position of the vehicle at the position 224, and step S30 for the POI 225. The record which set the kind of the facility specified by each is recorded on action log | history DB22. Further, when the type of the facility specified in step S30 is a home, it is determined that the user is leaving home from now, and the value of the trip ID 221 is updated.

In step S <b> 50, the control unit 10 performs an action estimation process by the action estimation unit 14. By this action estimation process, the action performed immediately before by the user or the action performed by the user in the future is estimated. The details of the action estimation process in step S50 will be described later with reference to the flowchart in FIG.

In step S60, the control unit 10 determines whether or not the action of the user can be estimated by the action estimation process of step S50. If the user's action can be estimated, the process proceeds to step S70. If the user's action can not be estimated, that is, if any estimation result is not obtained in the action estimation process of step S50, the process proceeds to step S140.

In step S <b> 70, the control unit 10 causes the message output unit 15 to specify a message corresponding to the user's action estimation result. At this time, the message output unit 15 compares the contents of the action type 242 and the action content 243 with respect to the contents of the action type 231 and the action content 232 in the record of the action estimation condition DB 23 representing the user's action estimated in step S50. Extract the records that respectively match from the message DB 24. Then, by referring to the contents of the message 244 in the extracted record, the message for the user's action result is specified.

In step S80, the control unit 10 determines whether a cancel instruction from the user for the message identified in step S70 has been received. At this time, the control unit 10 refers to the cancel 246 in the record of the message DB 24 representing the message identified in step S70, and determines whether or not a flag is set here to determine whether or not there is a cancel instruction for the message. judge. As a result, when the flag is set in the cancel 246, it is determined that the cancel instruction has been received, and the process proceeds to step S140 without outputting a message. On the other hand, when the flag is not set in the cancel 246, it is determined that the cancel instruction has not been received, and the process proceeds to step S90.

In step S90, the control unit 10 causes the message output unit 15 to output the message specified in step S70 from the speaker 70. However, when the message output at timing other than immediately after the user's action is estimated is specified at the output timing 245 of the record extracted at step S70, instead of outputting the message, according to the specified timing. Set the output timing. In this case, at the set output timing, the message output unit 15 outputs a message from the speaker 70. After the process of step S90 is performed, the process proceeds to step S140.

In step S100, the control unit 10 determines whether the ignition signal of the host vehicle is turned off. If the ignition signal of the host vehicle is off, the process proceeds to step S110. If the ignition signal is not off, the process returns to step S10.

In step S110, the control unit 10 acquires the current position of the vehicle from the vehicle position detection unit 30.

In step S120, the control unit 10 refers to the map DB 21 to specify a facility (POI) corresponding to the current position of the host vehicle acquired in step S110.

In step S130, the control unit 10 causes the action history recording unit 11 to record the user's action history in the action history DB 22 based on the current position of the vehicle acquired in step S110 and the facility specified in step S120. . At this time, the action history recording unit 11 uses the current date and time as the date and time 222, “disembarking” for getting on and off the vehicle 223, coordinate values corresponding to the current position of the vehicle at the position 224, and step S30 for the POI 225. The record which set the kind of the facility specified by each is recorded on action log | history DB22. When the facility specified in step S30 is set as the destination, a flag is set in the destination 226. After the process of step S130 is performed, the process proceeds to step S140.

In step S140, the control unit 10 performs an action estimation condition creation process by the action estimation condition creation unit 13. By this action estimation condition creation process, an action estimation condition according to the user's action history up to now is created and recorded in the action estimation condition DB 23. The details of the action inference condition creating process in step S140 will be described later with reference to the flowchart in FIG. After the process of step S140 is performed, the flowchart of FIG. 5 ends.

FIG. 6 is a flowchart of the action estimation process executed in step S50 of FIG.

In step S51, the action estimation unit 14 reads from the action history DB 22 the action history at the time of getting on immediately before getting on and getting off. Specifically, among the records recorded in the action history DB 22, the highest-ranked record in which the getting on / off 223 is "getting in" is read as the action history at the time of getting on immediately before. This record is a record recorded in the action history DB 22 at the immediately preceding step S40. Further, among the records recorded in the action history DB 22, the topmost record in which the getting on / off 223 is “getting off” is read as the action history at the time of the last getting off.

In step S52, the action estimation unit 14 calculates the stay time of the user at the facility corresponding to the current position from the action history at the time of getting on and getting off immediately before the load read in step S51. Specifically, the difference between the value of the date and time 222 of the record read as the action history at the time of the last ride and the value of the date and time 222 of the record read as the action history at the last alighting is obtained Calculate the time.

In step S53, the behavior estimation unit 14 acquires external information using the external information acquisition unit 12. Here, as described above, weather information and traffic information on the destination location, schedule information of the user, and the like are acquired as external information. In addition, it can be determined from the action estimation condition DB 23 as to which place is the destination place to acquire the weather information and the traffic jam information. That is, when there is a record in which the condition of the weather forecast or traffic jam information for any place is defined by the condition 233 in the action estimation condition DB 23, the weather information or traffic jam information matching the conditions is related to the destination location. It may be acquired as weather information or traffic congestion information.

In step S54, the action estimation unit 14 estimates an action using the action history at the time of getting in and off immediately before being read in step S51, the stay time calculated in step S52, and the external information acquired in step S53. It is determined whether any one of the action estimation conditions recorded in the condition DB 23 is satisfied. Here, the condition defined by the condition 233 of each record recorded in the action estimation condition DB 23 is referred to, and it is determined whether the immediately preceding action history matches any one of the conditions. As a result, if there is a matching condition, the process proceeds to step S55. If not, the process of FIG. 6 ends.

In step S55, the action estimation unit 14 identifies an action type and an action content indicating a result of the user's action estimation. Here, a record whose condition 233 is determined to match the previous action history in step S 54 is specified in the action estimation condition DB 23, and the contents of the action type 231 and the action content 232 of the record are referenced. Then, the action type indicating which of the user's last action and the future action is the estimation result and the specific action content are specified. As a result, an action estimation result according to the previous action history of the user can be obtained. After step S55 is executed, the process of FIG. 6 is ended.

FIG. 7 is a flowchart of the action estimation condition creation process executed in step S140 of FIG.

In step S141, the action estimation condition creation unit 13 reads the action history of the user recorded so far from the action history DB 22. At this time, only the action history recorded in a specific period may be read.

In step S142, the action estimation condition creation unit 13 determines whether or not there is regularity in the action history read in step S141. Here, as described above, the presence or absence of regularity in the action history can be determined in consideration of the recording frequency of the action history for the same facility, the time zone, the calendar, the regionality, and the like. As a result, when it is determined that there is regularity, the process proceeds to step S143, and when it is determined that it is not, the process proceeds to step S145.

In step S143, the action estimation condition creating unit 13 determines whether or not a record corresponding to the regularity determined from the action history read in step S142 exists in the message DB 24. Here, a record in which the action content 243 corresponding to the POI 225 of the action history that the action type 242 is “future” and is determined to be regular in step S142 is set in the records recorded in the message DB 24 Determine if there is. As a result, when the corresponding record exists, the process proceeds to step S144, and when it is determined that it does not, the process proceeds to step S145.

In step S144, the action estimation condition creation unit 13 creates an action estimation condition based on the regularity determined in step S142. Here, for example, the action estimation condition as defined in the condition 233 of the record shown in the fifth to seventh lines respectively in the action estimation condition DB 23 illustrated in FIG. 3 is created. The condition of the weather forecast in the sixth record and the condition of the congestion information in the seventh record are determined to be the position of the travel destination indicated by the position 224 of the action history determined to be regular, and the regular It may be determined from the action content 243 of the message DB 24 corresponding to the POI 225 of the action history.

In step S145, the action estimation condition creation unit 13 determines the presence or absence of the schedule information registered by the user. In the external information device such as a server or a portable terminal connected to the in-vehicle device 1 via the communication unit 40, when the user has registered the schedule information, the process proceeds to step S146, and when not registered, the step S148 Proceed to

In step S146, the behavior estimation condition creating unit 13 uses the external information acquisition unit 12 to acquire the schedule information of the user as external information.

In step S147, the action estimation condition creating unit 13 creates an action estimation condition based on the schedule information of the user acquired in step S146. Here, for example, the action estimation condition as defined in the condition 233 of the record shown in the eighth and ninth lines respectively in the action estimation condition DB 23 illustrated in FIG. 3 is created according to the acquired schedule information.

In step S148, the action estimation condition creating unit 13 records the action estimation conditions created in steps S144 and S147 in the action estimation condition DB 23. After step S148 is executed, the process of FIG. 7 ends. In addition, when neither step S144 nor step S147 is performed, ie, an action estimation condition can not be created, the process of FIG. 7 is complete | finished without performing step S148.

According to the first embodiment of the present invention described above, the following effects can be obtained.

(1) The in-vehicle apparatus 1, which is an information processing apparatus, records in the action history DB 22 the action history of the user regarding the visited place visited by the user in the past, and the action history recorded in the action history DB 22 And a message output unit 15 for outputting a message according to the user's behavior estimated by the behavior estimation unit 14. Since this is done, it is possible to provide user-friendly information.

(2) The action estimation unit 14 can estimate the past action of the user. Specifically, the action history recorded in the action history DB 22 includes the arrival date and time and the departure date and time of the visited place indicated by the date and time 222, and the facility type of the visited place indicated by the POI 225. The action estimation unit 14 estimates the past action of the user at the visited place based on the action history. Since this is done, it is possible to estimate the past behavior of the user, for example, the behavior immediately before the user, and to provide information according to the estimation result. Therefore, it is possible to provide information comfortable to the user.

(3) The action estimation unit 14 can also estimate the future action of the user. Specifically, the in-vehicle device 1 further includes an action estimation condition creation unit 13 that creates an action estimation condition based on the action history recorded in the action history DB 22. The action estimation unit 14 estimates the future action of the user based on the action estimation condition. Since this is done, it is possible to estimate the user's future behavior and to provide information according to the estimation result. Therefore, it is possible to provide information comfortable to the user.

(4) The action estimation condition created by the behavior estimation condition creation unit 13 can include the condition regarding the destination place where the user is going to go. The message output unit 15 outputs a message regarding the destination location. Since this is done, it is possible to output a message that matches the user's future behavior, and to provide useful and comfortable information for the user.

(5) The in-vehicle apparatus 1 further includes the external information acquisition unit 12 that acquires information on the destination location where the user is going to go, such as weather information and traffic congestion information, as the external information. The behavior estimation unit 14 can estimate the user's future behavior based on the behavior estimation condition created by the behavior estimation condition creation unit 13 and the information on the destination location acquired by the external information acquisition unit 12. Since this is done, it is possible to estimate the user's future behavior more accurately.

(6) The in-vehicle apparatus 1 further includes the external information acquisition unit 12 that acquires the schedule information of the user as the external information. The action estimation condition creation unit 13 can further create an action estimation condition based on the schedule information acquired by the external information acquisition unit 12. Since this is done, it is possible to more accurately estimate the user's future behavior using the created behavior estimation condition.

(7) The message output unit 15 suppresses the output of the canceled message when the output of the message is canceled by the user. Since this is done, it is possible to further improve the user's usability by not outputting any more messages that the user has determined to be unnecessary.

(8) The message output unit 15 can change the output timing according to the content of the message based on the information stored in the output timing 245. In this way, it is possible to output messages having different contents according to the user's future behavior at appropriate timing, which can further improve the user's usability.

Second Embodiment
Hereinafter, a second embodiment of the present invention will be described. In the present embodiment, an example will be described in which, when the user cancels the output of a message, the output of the message is suppressed in consideration of the attribute of each message. The configuration of the in-vehicle apparatus according to the present embodiment is the same as the configuration of the in-vehicle apparatus according to the first embodiment shown in FIG. 1 except for the structure of the message DB 24 in the storage unit 20. Therefore, in the following, differences in the structure of the message DB 24 will be mainly described.

In the on-vehicle apparatus according to the present embodiment, a message DB 24 A having a partially different data structure is stored in the storage unit 20 instead of the message DB 24. FIG. 8 is a diagram showing an example of the message DB 24A according to the second embodiment of the present invention. The message DB 24A further has an attribute 247 in addition to the fields of the message ID 241, the action type 242, the action content 243, the message 244, the output timing 245, and the cancel 246 described in the first embodiment.

The attribute 247 stores a value indicating the attribute of the message according to the record. In the example of FIG. 8, any one of the attributes “A”, “B”, “C”, “D”, and “E” is set in the attribute 247 of each record. The attribute to which each record belongs may be set in advance according to the action content 243 or the content of the message 244, or may be arbitrarily set by the user.

When outputting a message in step S90 in the flowchart of FIG. 5, the message output unit 15 refers to the attribute 247 and extracts each record having the same attribute as the message identified in step S70 from the message DB 24. Then, whether or not the flag is set in the cancel 246 in any of the extracted records is checked, and if the flag is set, the output of the message is suppressed. As a result, not only the canceled message but also a message having the same attribute as that of the canceled message is not output by the message output unit 15. For example, in the example of the message DB 24A of FIG. 8, it is assumed that the message “Can you do a good shopping?” Stored in the message 244 of the record in the second line is identified as the message corresponding to the user's behavior estimation result. In this case, since the flag is set in the cancel 246 of the record in the third line in which the same attribute "B" is set in the attribute 247, the message output unit 15 does not output the above message.

According to the second embodiment of the present invention described above, the message output unit 15 further suppresses the output of the message having the same attribute as the canceled message. Since this is done, it is possible to further improve the user's usability by not outputting any message similar to the message that the user has determined to be unnecessary.

The first and second embodiments described above may be modified as follows.

(Modification 1)
The message output unit 15 may output the message in a form other than voice, such as screen display by the display unit 50. Also, the voice and the screen display may be switched as appropriate. For example, a message having a predetermined number of characters or less may be output by voice, and a longer message may be output by screen display. Furthermore, images and videos may be combined.

(Modification 2)
A part or all of the functions of the in-vehicle apparatus 1 may be realized by a server. The in-vehicle apparatus in that case may have at least a function of performing information communication with the server and a function of outputting a message. For example, the on-vehicle apparatus detects the on / off of the ignition signal of the own vehicle and transmits the position of the own vehicle to the server, and the receiving unit for receiving the message transmitted from the message output unit 15 of the server; It can be configured by a message reproduction unit that reproduces the message and presents it to the user.

(Modification 3)
In the action estimation unit 14, when a plurality of action estimation conditions are simultaneously satisfied and a plurality of action estimation results are obtained simultaneously, the message output unit 15 may continuously output each message. Also, priority may be set for each message, and messages with high priority may be output with priority.

(Modification 4)
The message content may be transmitted from the in-vehicle apparatus 1 to an information terminal such as a smartphone possessed by the user, and the message may be output from the information terminal. For example, by connecting the in-vehicle apparatus 1 and the information terminal via a communication line such as a wireless LAN or Bluetooth, it is possible to transmit a message from the in-vehicle apparatus to the information terminal.

(Modification 5)
In the above embodiments, the user instructs to cancel the message using the operation input unit 60. However, the user may instruct to cancel the message using another input unit, for example, voice or gesture. In that case, the on-vehicle apparatus may include a microphone for detecting a voice, a camera for detecting a gesture, or the like, or may be mounted on a vehicle.

(Modification 6)
In each of the above embodiments, the provision of information by the in-vehicle device 1 which is an information processing device mounted in a vehicle has been described, but the present invention is not limited to the in-vehicle device. The present invention is also applicable to other information processing apparatuses as long as the position of the user is detected and the action history is recorded, the action of the user is estimated based on the action history, and the message is output.

The embodiments and various modifications described above are merely examples. The present invention is not limited to the above embodiment as long as the features of the present invention are not impaired, and other embodiments considered within the scope of the technical idea of the present invention are also included in the scope of the present invention. .
